Application April 1, 1946, Serial No. 658,644

Our invention relates constructions, but more particularly to features of construction in metal screens.

An object of our invention is to provide a window screen that comprises both a screen surface and a burglar proof protecting grill.

Another object of our invention is to provide a clamping type frame designed to hold frictionally a layer of screen wire and a protecting guard member in assembled positions, a clamping member which does not require the use of any screws, bolts, or the like in the assembly of the same.

Another object of our invention is to provide means for mounting a metal screen or other type of screen in a window frame, the means including to sash, door, andscreen' 4 Claims. (01.160-394) a pair of stationary studs extending out of one side edge of the screen in the plane of the screen adapted to fit into socket holes formed in one side of a window frame, and provided with a pair of spring pressed plungers terminating in studs that are adapted to fit in a second pair of sockets formed in the opposite side wall of the window frame.

Our invention in screens, generally speaking, inheres in novel framing elements for use in assembling a layer of screen wire and'protecting mesh together. The framing elements are made out of a springy sheet metal material cut into strips two or three inches wide and then bent into wedge shaped channel members with the channel walls inclined inwardly toward each other. When the channel walls are forced over the edges of the protecting grill, with portions of the screen lapped over the same, the walls of the channel in the assembled clamping position are left resiliently spread. These springy wedge shaped channel frame members grip the edges of the assembled layer of screen and the protecting grill over which edge portions of the soreenlayer are folded. The channel members maintain their grip on the screen and edge of grill sandwiched in between layers of the screen throughout the entire life of the metal screen.

No screws or bolts are needed in our type of metal screen construction. When the end and side members of the channel frame are driven into place they are soldered together along their joining lines.

In the drawings,

Figure 1 is a plan view of a metal screen made according to the teachings of our invention shown in its assembled position in a window frame.

Figure 2 is an enlarged plan view of a retaining 2 means incorporated in the metal screen illustrated in Figure 1.-

Figure 3 is an enlarged cross-sectional view of a frame construction feature ofthe screen illustrated in Figure 1 taken on line 3-3 of Figure 1,

and, I

Figure 4'is an enlarged plan view of a key used to operate a retaining means'incorporated in the screen illustrated in Figure 1.

Referring to the drawing numeral Ill designates a grill which is preferably made out of a high carbon steel, hard enough to resist even a hacksaw blade. The grill [0 is made up of diagonally extended rods H which are welded to a rectangular rod frame l2 which includes top and bottom end members 13, a right-hand side member i 4 and a left-hand side member IS. The lefthand side member I5 is made up of three pieces,-

a central portion I6, an upper end extension If and a lower end extension I8.

A 'layerof screen mesh l9 of greater area than the grill [0 is laid on the grill H! in the assembly of the screen. Portions of the screen I9, shown folded over the end members H! of the rod frame l2 and marginal portion of the diagonally extending rods I I as best seen in Figure 3, are desig nated by numeral 26. The portions ofthe screen mesh l9 folded over the right-hand side member l4 and the left-hand side member [5 are designated by numeral 2|. When the screen mesh l5 isa'ssembled on the grill [0, in the manner above described, the members of the clamping frame 2? are pressed on, which clamping frame is made up of a pair of "separate channel shaped end members 23 including a base portion 24 from which extends inwardly inclined side walls 25 and side channel members 26 including base members 2? and side walls28. t J

When assembled,'the side member 26 and end member 2 3 are soldered together along the solder s"- improve the looksof' the frame The members of the frame, side members 26 and end members 23, individually maintain their grip on the edge portion of the assembled screen mesh [9 and the grill l0. Each member of the frame is made out of a strip of springy sheet metal material.

During the assembly of the end members 23 and the side members 26, as illustrated by Figure 3, the base member 24 of the end member 23 is forced down into pressing contact with the portion of the screen mesh l9 that is folded around the end member l3 of the rod frame l2. To start the end member 23 on the assembled screen mesh l9 and grill In the side walls 25 at one end must The soldering is, done principally to 26 are all maintained-impressing contact Withthescreen mesh l9 due to the resliency of the clamp ing frame 22.

The means and method of mounting the above described metal screen, or for that matter a wooden screen, or other prior art typeof-screen,

we will now explain.

On the right-hand side member l l of therod frame l2 a pair of studs 30 are welded. The studs 30 extend through holes made in the base members 21 of the side members 26. The studs 36 extend in. the plane of :the screen. and. at, a :right angle to the righthand side memberlficof fithe clamping frame 22; The. studs130 are-adapted-to fitinto. sockets .3 formed inzthewindow :frame which, sockets S are preferably lined withtubular metal socket liners L. The same type of sockets S and socketlinersL; ar e,:=employ,ed orr the lefthandside of the windowframe -W to receive, the locking studs 36 ofrtheplungerstt:offuhe locks El which we willnow described in; detail.

As a means. of;holding;the;metal :scrleen; in the window frame -W we :employ, a pair: of; duplicate locks: 3 Lybothz of which, are rlocated :one', the. .lefthand ,sideof the screen ,as seen-in; Fignre;1, -only one of v which we will" describe. The, lock ;3 l ,in-.

The.- compression spring 3 9, interposed, between I the internally threaded boss 31 formingandntegral part of the plunger 35- and. the washer- 33, urges the plunger35 .into locking pos tion; a position-- in whichthestud 36- has ibeenmoved into the socket-S.

To remove the locking-,stud-fi the plungenjiof which it forms an integral part,: m 1st .be pulled out against .the pressure of the compression spring. 39; This isdonebymeans of..a;threaded rod key 40 provided-with .a gthreadedend portion 4| adapted .to engage.the.internall threaded boss 31, The rod isterminated,atitsothenfindifl a 4 loop 42 adapted to be gripped by the fingers of the operator.

During the placing of the screen in the window frame W and the removal of the sam both of the plungers 35 of the two locks 3| are withdrawn by a pair of keys M). We have purposely hidden the shells 32 of the locks 3! in between the side walls 28 of the side members 26. The outer end of the shell 32 is positioned inwardly of the edges of the side Walls 28 so that even the keyhole, the opening defined by the Washer 33 is hidden from view.

rThesscreen frame proper may be made of any springy metal sheet material. A galvanized steel .:material or a bronze or a copper material are .-pr'eferred since such materials resist rust.
